2x2 + 7x - 15 = (2x - 3)(x + 5)
7x2 -4x -5x2 +2x = 2x2 -2x
2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
((15xy2)/(x2+5x+6))/((5x2y)/(2x2+7x+3)) =(15xy2/5x2y)*(2x2+7x+3)/(x2+5x+6) =(3y/x)*(((2x+1)(x+3))/((x+2)(x+3) =(3y(2x+1))/(x(x+2)) =(6xy+3y)/(x2+2x)
(x + 1)(2x + 5)
2x2 + 7x - 15 = (2x - 3)(x + 5)

7x2 -4x -5x2 +2x = 2x2 -2x
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
(x + 5)(2x - 3)
When you subtract 7x^2 from 5x^2, you get -2x^2.
(x - 2)(2x - 3)
No
2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
